I swear I have tried everything and can not get the ESC to bind to the Airtronics M11x? I had this issue with my Spektrum turned out to be the throttle expo was to low in the settings, dialed it up and it worked. I tried that with the M11x and still nothing.

Anyone have any suggestions to try?

Thanks!

did you set your throttle to normal mode? 4pk required reverse mode and m11x required normal mode, please check.

I checked and it's on normal mode... Going to solder up my other RSP and see if it's actually the speedo that is bad.

Thanks for your help!

sometimes these newer esc's don't like it when the epa (end points) are not set even ie: 160 high/140 low. Try setting them both even.
